Simple question guys and girls. I have a large tv (36 inch widescreen) and a new high end projector, probably at the end of this week. I have noticed that my average terestrial signal is only okay on large screens. How much better is Sky or Ondigital (or whatever they are called now)? Is it better? A connections would be the best available (RGB?). I am a quality sort of guy. Would I see a benefit? I am after the best picture and sound quality posible.
